MOLD FOR MAKING GARBAGE-RECEP'IACLES AND THE LIKE;

Specification of Letters Patent. Patented Feb. 25, 1919.

Application filed June 19, 1917. Serial No. 175,589.

and useful Improvements in Molds for Making Garbage-Receptacles and thelike, of which the following is a specification.

My invention relates to improvements in molds for making garbagereceptaclesand the like, and has for its object the provlsion of asimple and efficient construction of this character which is readilycollapsible and by means of which articles, such as garbage receptacles,may be formed with great economy and expedition.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanylngdrawings forming a part of this specification, and 1n which,

Figure 1 is a longitudinal vert1cal section of a form embodying myinvention,

. Fig. 2, a top plan view of the same, Fig. 3, a front end view of thesame,

Fig. 1, a vertical transverse section of the same,

Fig. 5, a perspective view of a garbage receptacle formed in the formillustrated 1n Figs. 1 to 4 inclusive,

Fig. 6, a vertical longitudinal sectlon of said receptacle,

Fig. 7, a horizontal section taken on line 77 of Fig. 6, and v Fig. 8, avertical section taken on line 8-8 of Fig. 6.

The preferred form of construction as illustrated in the drawings,comprises a suit able base member 9 having a raised central portion 10as indicated. All outer form member is arranged upon said base memberand consists of side members 11 and front and rear members 12 and 13respectively positioned on said base member agalnst the.

sides of the elevated portion 10, the end members being grooved toreceive the ends of the side members and the side members being providedwith vertical angle irons 14 adapted to be clamped to the ends of thefront and rear members by means of wood clamps 15 as indicated. The sidemembers 11 are provided with upward extenslons 11 at their rear portionsand a cross strlp 16 grooved to receive the forward end of the sions 17to'provide door receiving extensions 11, the extensions 11'beingprovided with angle irons 1 1 by means of which the strip 16 may beclamped in place. a

A hollow core member 17 is arranged to be suspended within the outerform member above open at the bottom as indicated to permit of finishingof the upper surfaces of the bottom of the receptacle formed in theform. The core member 17 projects at its forward end through a suitableopening provided in the front wall 12 and is secured in place at the topand sides by means of angle irons 18 as indicated. A strip 19 isarranged across the inner upper portion of the front wall 12 and carriesan angle iron 20 at its upper rear portion, said strip serving to form aspace for the reception of the door of the garbage receptacle formed inthe form and the angle iron 20 serving to form a recess for thereception of a portion of said door. Angle irons 20 are arranged alongthe sides of core member 17 to provide door receiving grooves in thesides of the receptacle formed and a strip 21 is arranged across thebottom of the opening in the front wall 12 to form a beveled ledge atthe bottom of the door space as shown. The core member 17 is supportedatthe rear by means of a strip 22 secured to the rear wall 13andco-extensive with and secured to the rear of said core member asindicated, the core member being provided with an upward rear extension17 for the purpose. Angle irons 23 are arranged about the sides andforward portion of the extengrooves and-the strip 22 forming a doorreceiving space, as indicated. By this arrangement it will be observedthat when the hollow described, said core member being spaces betweenthe outer form member and the inner core member are filled with concreteor other plastic material, a garbage receptacle 24 will be producedhaving door spaces 25 and 26 grooved for the reception of doors 27 and28, as indicated.

In use the mold is assembled as indicated in the drawings, and thehollow spaces between the Walls thereof filled with a cement or concretemixture in a semi-liquid or plastic state, sufficiently liquid orplastic to flow under the strips 20 and 22 and to be shaped thereby.When the material thus inserted is sufficiently set the form or mold isremoved therefrom. The outer portion of the mold is preferably removedfirst,

' claim as which may be readily done by loosening the clamps 15 as willbe understood. Thereupon the inner form member or core is removed. Thisis preferably accomplished by first loosening the top of the forwardportion of the core member which upon being slightly tilted may bereadily removed through the open end thereof. Then the main sideportions of the core member are removed by releasing the same from therear wall and upward extension 17 and drawing the same forwardly. Thenthe rear wall and upward extension may be readily removed by drawing thesame out vertically, and should there be any sticking, these parts maybe readily taken apart to facilitate suchremoval. The receptacle is thenlifted from the base member of the mold, when it is completed and readyfor use.

While I have illustrated and described the preferred form ofconstruction for carry- 1n m invention into eifect this is ca aable ofvariation and modification without departing from the spirit of theinvention.

I, therefore, do not wish to be limited to the precise details ofconstruction set forth, but desire to avail myself of such variationsand modifications as come Within the scope of the appended claims.

Having described my invention What I new and desire to secure by LettersPatent is:

1. 'A' construction of the class described comprising an outer formmember open at the top; and an inner core member suspended within saidouter form member and projecting through the forward wall thereof; andangle irons arranged on the sides of said core member and adjacent theforward end thereof and poistioned to form door guiding grooves in theinner walls of the molded article, substantially as described.

. 2. A construction of the class described Copies 01' this patent may beobtained for five cents each, by addressing the comprising an outer formmember open at the top; an inner core member suspended within said outerform member and projecting through the forward wall thereof; and asuspending strip co-extensive with the rear upper edge of said coremember and spanning the space between the rear side of said core memberand the rear wall of said outer mold member, substantially as described.

3. A construction of the class described comprising an outer form memberopen at the top; an inner core member suspended within said outer formmember and projecting'fthrough the forward wall thereof; angle ironsarranged on the sides of said core member and adjacent the forward endthereof and positioned to form door guiding rooves in the inner walls ofthe molded artidle; a strip arranged across the top of said core memberadjacent the forward edge thereof; and a separating strip co-extensivewith the rear upper edge of said core member and spanning the spacebetween the rear side of said core member and the rear wall of saidouter mold member, substantially as described.

4. A construction of the class described comprising an outer formmember, made up JOSHUA R. H. Por'rs, HELEN F. LILLIS.
